I mean, personality disorders are all about problems in close interpersonal relationships (or lack of interest in such relationships, in schizoid personality disorder), and trust is always really relevant in such relationships, so I think this could be a helpful lens of looking at things. At the same time, I’d be very surprised if you could derive new helpful treatment approaches from this sort of armchair reasoning (even just at the level of hypothesis generation to be subjected to further testing).
Also, some of these seem a bit strained:
Narcissistic personality disorder seems to be more about superiority and entitlement than expecting others to be trusting. And narcissism is correlated with Machiavellianism, where a feature of that is having a cynical worldview (i.e., thinking people in general aren’t trustworthy). If I had to frame narcissism in trust terms, I’d maybe say it’s an inability to value or appreciate trust?
Histrionic personality disorder has a symptom criterion of “considers relationships to be more intimate than they actually are.” I guess maybe you could say “since (by your hypothesis) they expect people to not care, once someone cares, a person with histrionic personality disorder is so surprised that they infer that the relationship must be deeper than it is.” A bit strained, but maybe can be made to fit.
Borderline: I think there’s more of pattern to splitting than randomness (e.g., you rarely have splitting in the early honeymoon stage of a relationship), so maybe something like “fluctuating” would fit better. But also, I’m not sure what fluctuates is always about trust. Sure, sometimes splitting manifests in accusing the partner of cheating out of nowhere, but in other cases, the person may feel really annoyed at the partner in a way that isn’t related to trust. (Or it could be related to trust, but going in a different direction: they may resent the partner for trusting them because they have such a low view of themselves that anyone who trusts them must be unworthy.)
Dependent: To me the two things you write under it seem to be in tension with each other.
Edit:
Because it takes eight problems currently considered tied up with personal identy and essentially unsolvable [...]
I think treatment success probabilities differ between personality disorders. For some, calling them “currently considered essentially unsolvable” seems wrong.
And not sure how much of OCPD is explained by calling it a persistent form of OCD – they seem very different. You’d expect “persistent” to make something worse, but OCPD tends to be less of an issue for the person who has it (but can be difficult for others around them). Also, some symptoms seem to be non-overlapping, like with OCPD I don’t think intrusive thoughts play a role (I might be wrong?), whereas intrusive thoughts are a distinct and telling feature of some presentations of OCD.
